What is a solenoid? Compare themagnetic field produced by a solenoidwith the magnetic field of a barmagnet. Draw neat figures and namevarious components. |

Answer» The solenoid is a long cylindrical coil of wire consisting of a large no. of turns bound together very tightly.Note: The length of the coil should be longer than its diameter. (Or)Solenoid is a coil of a number of turns of insulated copper wire closely wrapped in shape of a cylinder. Magnetic field around a current carrying solenoid is as shown in the figure. Theses appear to be similar to that of a bar magnet. One end of theSolenoid behaves like North Pole and the other end behaves like the South Pole. Magnetic field lines inside the solenoid are in the form of parallel straight lines.This means that the field is same at all the points inside the solenoid. When soft iron rod is placed inside the solenoid, it behaves like an electro magnet. The use of soft iron as core in the solenoid produces the strongest magnetism. |
